ACM (Aluminium Composite Material) rainscreen cladding is a lightweight flat sheet panel that consists of a fire resistant core which is faced with two thin sheets of aluminium. The aluminium is bonded onto the core during the manufacturing process and it is virtually impossible to separate the layers of material once they have been bonded together. A wide range of aesthetically pleasing colour finishes are available in both products. As a cladding material the product can be cut to size and used flat or alternatively folded at the edges to make trays which can the be screw fixed or hooked onto a sub-frame. Leading brands of ACM include; Alucobond / Vitrabond / Elval.
Material Properties & Characteristics
Panels are weather resistant, impervious to rain and can cope with extreme climatic conditions;
